Three Sisters, One Pathway


      We present the first reported case of an entire family, 3 sisters, all presenting with symptomatic atrioventricular reciprocating tachycardia during a 15-year period, all were found at electrophysiological study to have identically located left lateral accessory pathway, all successfully treated with radiofrequency ablation. This rare familial clustering suggests a genetic contribution to pathway formation.


      Nous présentons le premier cas rapporté d'une famille entière, soit trois (3) sœurs présentant chacune une tachycardie atrioventriculaire réciproque symptomatique durant 15 ans, qui a été trouvée lors de l'étude électrophysiologique de manière identique dans les voies accessoires latérales gauches. Elles ont toutes été traitées avec succès par l'ablation par radiofréquence. Cette agrégation familiale rare suggère une contribution génétique à la formation de voies.
